A specimen of Facciola’s sorcerer, Facciolella oxyrhyncha (Bellotti, 1883), was caught for the first time in the central Aegean Sea, on January 2007 by a commercial bottom trawler at a depth of about 230 m on the muddy bottom of Southern Sigacik Bay, Aegean Sea, Turkey.

A new opecoelid trematode, Peracreadium akenovae sp. nov., is described from the highfin moray eel Gymnothorax pseudothyrsoideus (Bleeker) (Anguilliformes; Muraenidae), collected from Moreton Bay off southeast Queensland, Australia. The new species is distinctive in its body shape, transversely elongate irregular testes, vitelline follicles interrupted at the level of the ventral sucker, and diverticulate excretory vesicle. The Muraenidae is a new host family for Peracreadium Nicoll, 1909. Peracreadium is the seventh opecoelid genus reported from temperate eastern Australian marine fishes and this is its first report from Australian waters.

In 2008, a specimen of a pignosed arrowtooth eel, Dysomma brevirostre (Facciolà, 1887), was caught by a bottom trawling operation at Sigacik Bay (Aegean Sea), Turkey. Total length (TL) and weight of the fish were 23.2 cm and 2.00 g, respectively. This study reports the first record of D. brevirostre from the Aegean Sea and logs a new species for the Turkish Ichthyofauna.

Following a series of surveys with bottom longlines and fish traps along the island slopes off the archipelagos of Madeira, Canaries and Cape Verde, and with bottom trawls along the coast of Morocco and Western Sahara between 2004 and 2006 many specimens of Synaphobranchus were caught, revealing the presence of two species. Based on these specimens and Museum preserved specimens from this area grey cutthroat, Synaphobranchus affinis Gunther, 1877, is recorded for the first time from off Portugal, Madeira archipelago, Great Meteor Seamount, Canary Islands, Morocco, Western Sahara, Cape Verde Islands, and Senegal. It is confirmed that S. kaupii is also conspecific in this area. Meristic and morphometric data of the specimens studied are also presented.

Cucullanus hainanensis sp. nov., collected from Muraenichthys gymnopterus (Bleeker) (Anguilliformes: Ophichthidae) in the South China Sea, was described using both light and scanning electron microscopy. The new species can be readily distinguished from its congeners by the large pseudobuccal capsule, the position of excretory pore and deirids, the length of spicules (0.64–0.76 mm, 5.84–6.67% of body length) and gubernaculum (0.21–0.24 mm), the number and arrangement of caudal papillae and the particular morphology of cloacal region in male. The new species was also characterized using molecular methods by sequencing and analysing the small subunit (18S) and the second internal transcribed spacer (ITS-2) of nuclear ribosomal DNA (rDNA). In addition, Cucullanus muraenesocis (Yin et Zhang, 1983) was regarded a homonym of C. muraenesocis Yamaguti, 1961, and a new name, Cucullanus wangi nom. nov. was given to it.

Background. The European eel, Anguilla anguilla (L.), is considered an endangered species and a series of protective measures have been implemented within the European community in order to enhance natural stocks. Restocking natural habitats with larger eels reared from the glass-eel stage in recirculated farming systems may be one solution. Gill diseases caused by monogenean parasites of the genus Pseudodactylogyrus are currently causing morbidity and mortality in these farms and previously applied standard treatments have recently failed. Therefore the applied control methods should be verified and novel solutions proposed. Materials and methods. Eels infected by Pseudodactylogyrus anguillae were obtained from a typical recirculated eel-culture system which had been treated regularly but recently unsuccessfully with benzimidazole anthelmintics. In the laboratory infected eels were subjected to bath treatments with flubendazole (5 or 10 mg · L–1) or praziquantel (5 or 10 mg · L–1) for 24 h at 25ºC and parasite infections were recorded three days post-treatment. Results. Gill monogeneans, Pseudodactylogyrus anguillae, were not controlled by the anthelmintic flubendazole at any of the dosages tested whereas praziquantel showed a significant effect when used as bath (5 and 10 mg · L–1). Conclusion. The failure of flubendazole for control of pseudodactylogyrosis may result from selection of anthelmintic resistant parasite strains due to use of benzimidazoles for decades. Future treatment regimes during acute outbreaks may be based on praziquantel. A risk for future continued selection for anthelmintic resistance exists and supplementary non-chemical methods (mechanical and biological) in rearing of European eel should be emphasized in the future management practice of eel.
